The following properties are included: density, pressure, internal energy, enthalpy, entropy, heatcapacity at constant pressure, heat capacity at constant volume, speed of sound, and the Joule-Thomsoncoefficient, in both single-phase states and along the liquid-vapour saturation boundary. The numericaldesignation of these refrigerants is that defined in ISO 817.【中国标准分类号】: G17;J73【国际标准分类号】: 71_100_45【页数】: 70P;A4【正文语种】: 英语
